Now is the time to plant grass seed, perennials, bulbs, trees (with exception of some broad-leaved evergreens and conifers) and shrubs. With moisture & moderate temperatures, roots have an excellent chance to get established before winter freezes. When planting trees, dig a hole no deeper & even a little shallower than the root ball, but 3 to 4 times as wide. If you dig a hole too deep and backfill before placing a tree is the hole, this invites settling. With water and time, the tree could sink below ground level – almost always fatal to a tree. Plant azaleas with top of root ball above the soil. Mulch newly planted trees and shrubs, but do keep it off of stems of trees! Spread compost in the garden now, it’s good for plants & empties mulch bin or pile to make room for fall leaves, Remove old annuals, divide Hemerocallis(daylily), Siberian iris, Astilbes (need division every 3-4 years) Coral bells. Remove spent plants and stems from the garden – disinfect pruners before using from one plant to another to avoid spread ing disease. Cut all the brown foliage from peony plants right down to ground level. Disease can over-winter on these leaves. Do not put diseased plants on the mulch pile. Resist the urge to prune now as the tender new growth may not harden off sufficiently before cold weather arrives – an exception: Hydrangea Annabel. If your plant is flopping over, it can actually be cut to the ground, or to 18” to 24” allowing stems to thicken & provide more support for the large blooms, anytime now thru late winter. Hydrangea Paniculata, or PeeGee can be cut back to 18”-24” to rejuvenate shrub & limit its size. This is only form of hydrangea that can be pruned into a tree form. Do not prune other hydrangeas now as they set buds on current season’s growth– wait until just after they bloom. You can remove spent blossoms, but some theorize that these dead blossoms help protect the buds below during the winter. Now is the time to dry hydrangeas – when the color has turned lime green on Annabel
They are ready to bring in and place in a vase with or without water. You can also cut blossoms from other hydrangeas.
Plan to cut grasses in the late winter – these old stems help to insulate the root ball.
It is best not to prune roses heavily now…wait until early spring. Do however, cut off any dead wood. When leaves have dropped, be sure to rake all dead ones from underneath and deposit in trash – not mulch pile. If we have a very cold, then warm winter, this does lots of damage to roses, so heavily mulch them after the first frost.
